Kingdom of Thrace

The Kingdom of Thrace was a Hellenistic empire that was founded by Alexander the Great's general Lysimachus in 306 BC in Thrace and Tribus Getae. The Thracian domains expanded northwards to the Ukraine but all of these were taken by the Roman Republic after a series of military campaigns as of 207 BC.

History
The Kingdom of Thrace was said to be a Hellenistic kingdom but was originally a confederacy of Odrysian tribesmen, the Thracians. The Thracians were a group of barbarians subdued by Alexander the Great in 336 BC, and subsequently Hellenized, and brought under the rule of Lysimachus following his death. The Kingdom of Thrace evolved into a fusion of Greek and Barbarian cultures under Lysimachus' rule, and in 281 BC, it was defeated by the Seleucid Empire at the Battle of Corupedium, and they might have been destroyed had it not been for Seleukos' assassination by Ptolemy of Macedon. Thrace was at its pinnacle in the 250s BC; having conquered the Kingdom of Dacia and some rebel tribes, they had control of most of The Balkans, but the Roman Republic moved in and conquered all of their interests by 207 BC.
